Catalyzes the transfer of sialic acid from a CMP-linked sialic acid donor onto the terminal sialic acid of an acceptor through alpha-2,8-linkages. Is active with alpha-2,3-linked, alpha-2,6-linked and alpha-2,8-linked sialic acid of N-linked oligosaccharides of glycoproteins and glycolipids. Displays preference for substrates with alpha-2,3-linked terminal sialic acid. It can form polysialic acid in vitro directly on alpha-2,3-, alpha-2,6-, or alpha-2,8-linked sialic acid.
Gene References into Functions
Data indicate that the crystal structure of ST8SiaIII sialyltransferase show a cluster of polysialyltransferase-specific structural motifs that provide an extended electropositive surface groove for binding of oligo-polysialic acid chain products. PMID: 26192331
These results suggest that the expression of hST8Sia III gene via the PI-3K signaling pathway is enhanced during KCl-induced differentiation of U-87 cells by increasing expression of beta-tubulin III. PMID: 16643848
